Tailor Welded Blanks

Optimized sheet metal parts

Made to fit

Tailor Welded Blanks are made from individual steel sheets of different thickness, strength and coating which are joined together by laser welding. These tailor-made products ensure that the finished part features the right material in the right place. A key advantage is weight reduction. In addition, the structural and crash performance of the vehicle body is improved: thicker or higher-strength materials can be used in highly stressed areas, while thinner sheets or deep-drawing grades can be used in other areas.

This targeted approach to tailor materials further reduces costs. Expensive materials are only used where they are needed. This allows a flexible part design that fully optimizes the material properties available.

The use of tailored solutions eliminates the need for additional reinforcements and overlapping joints in the body; saving material, eliminating operations, and further reducing total weight. In this way, tailored products are a significant enabler to meet specified CAFE targets. Reducing the weight of a vehicle by 25% results in a 20% reduction in fuel consumption.

Advantages of tailored products

The targeted combination of different steel grades and thicknesses provides tailored products with their classic advantages:

  • Lower weight
  • Reduced part costs
  • Optimized crash performance through the use of high-strength materials
  • Optimized material utilization through efficient nesting
  • Lower capital costs for tooling and assembly lines through reduction in number of parts
  • Lower product design costs due to part consolidation
  • Elimination of overlapping joints improves corrosion behavior
